GRAIN-BINDER.

SPECIFICATION forming part of Letters latent No. 651,770, dated June 12,1900. Application filed June 19, 1899. Serial No. 721,066. (No model.)

To aZZ whom it may concern:

Be it known that I,JOHN W. PRIDMORE, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Grain-Binders; and I dohereby declare the following to be afull,clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

The improvement has reference to grainbinders in general, but moreespecially to a type that are now well known and wherein theknotter-operating shaft is intermittently driven from thecontinuously-running packershaft through the intermediacy of a verticalshaft having a miter-gear connection at its upper end with a drive-wheelon the shaft. An example of this type is embraced in the patent grantedto the McCormick Harvesting Machine Company, assignee of Henry E.Pridmore, March 29, 1898, No. 601,609, and the present improvement isherein illustrated and described as applied to themachine of thatpatent, though without intending thereby to restrict its applicationtothat or any other class of machines. In the operation of thesemachines in the field there is a tendency, due to the high speed atwhich the binder mechanism is run, as well as the constant jolting andjarringof the machine, for the trip-stop to rebound on being returnedinto the path of the revolving trip-dog as the bundle is being ejected,and as this dog revolves very rapidly the result is that thebindermechanism is not thrown out of action at the completion of eachbundle, as it should be, and the binding operation is immediatelyrepeated before sufficient grain has accumulated to form another bundle.It is the object of my invention to prevent this rebound of thetrip-stop by holding it down until the trip-dog has struck it anddisengaged the shaft which drives the knotterv-shaft; and the inventionconsists, broadly, in arranging a projection or part of the drive-wheelof the knotter-operating shaft in such relation to the parts connectedwith the trip-stop that at the appropriate point in the revolution ofthe wheel it will strike an arm connected with the stop and hold it downjust long enough for the revolving dog to hit it and unclutch thebinder.

The invention also includes certain specific arrangements of partswhereby the improvement has been adapted to the machine of the patentabove referred'to.

In the accompanying drawings, Figure 1 is an end view of so much of thebinder-operating mechanism as is necessary to an understanding of theabove described improvement. Fig. 2 is a side View thereof, thehorizontal members of the binder-frame being broken off; and Fig. 3 is asectional detail of the lower end of the lever for operating thetrip-stop.

Referring to the views, A denotes the overhead tubular arm of thebinder-frame, D the corresponding member of the frame underneath thebinder-deck, and E the vertical member joining these two arms togetherand preferably forming a housing for the vertical shaft by means ofwhich the wheel B of the knotter-operating shaft 0 is driven from apinion on the continuously-running packershaft. The wheel B is driven bya pinion on the upper end of the vertical shaft, as in theabove-referred-to patent, and on the lower end of the shaft there is thesame pinion E, clutch-box c and connecting-sleeve e. The clutch trip-dogJ is also the same as in the above-mentioned patent, as well as themanner in which it connects and disconnects the clutch-box from theshaft.

The needle-shaft isdenoted at G, and the arm I and link H constitute themeans whereby the needle is given the proper reciprocation by. the wheelof the knotter-operating shaft 0.

K denotes the trip-finger, and K its shaft. On the end of the shaft Kthere is secured the stop-arm K the construction and manner of operatingwhich are the same as in the previously-patented machine.

The trip-stop is denoted by K. It is simplya projection on the outer endof the stoparm K and as the arm rises and falls it is thrown into andout of the path of rotation of the trip-dog J in a manner now wellunderstood. The lever for operating the stop-arm is shown at L. It issubstantially the same as the lever of the above-mentioned patent Too 6oasthe two cams are 'incontact.

and has a roller l on its upper end running in a carn-nace 1 on thewheel B. The lever carries a -slide'D, and on the lower end of the slidethere is a pin Z carrying a roller Z,

5 which as the arm L is vibrated on its pivot Z works to and fro in acam-slot Z in the stoparmK I l The slide D isipresseddownwardly on the jlever L by means of a strong spring D which re reacts between aprojection Z at the lower end of the slide and an abutment on the leveror binder-frame above. The object of allowing he' a t D to s i e a d dinitd by spring-pressure'is to permit the trip-Jinr 5 ger K to yieldagainst the pressure ofthe grain and rock the shaft K, so as to raisethe tepzerm K n ele s he dog l o, 9 as to'conipress the bundle witha'yieldingpres: I
